Handshakr
OperatingB2B marketplace where buyers and sellers are matched through AI-powered digital twins. Built for operators who'd rather close than browse.
Cardiff Giant Ventures
We build software that earns its place.
The venture studio inside Cardiff Giant Holdings. We build and operate SaaS platforms, and advise the founders and operators building alongside us. Everything here exists to test, validate, or scale a decision.
Build
We design, ship, and operate software platforms — not prototypes. If it can't survive contact with real operators, it doesn't ship.
Advise
We work with founders and operating teams on the decisions that compound: what to build, what to kill, and what to scale.
Hold
Winning platforms stay in the portfolio and feed the next build. Insight becomes IP. IP becomes platforms. Capital is recycled.
How we work
This is not a portfolio. It is a system.
Most studios collect ideas. We compound them. Advisory work surfaces real operating problems. Those problems become frameworks. Frameworks become products. Products that earn their place become companies — and the lessons from every build, win or loss, fund the next one.
That discipline shows up in what we keep and what we let go. Twenty-three properties sit in the studio today. Some are live and growing. Some are still being built. A handful are listed for sale because they proved their point and don't need us to operate them. None of them are vanity.
Platforms
A working stack, not a wishlist.
Software for founders, operators, and the businesses they run. Built in-house, used in the field, sharpened by the consulting work.
Homestrate
OperatingTrack a home move like a delivery. One shared timeline for buyers, sellers, and conveyancers — so nobody's left guessing.
Decision Protocol
OperatingThe DecisionOps platform that makes enterprise decision flow visible, accountable, and governable.
Haptyq
BuildingRevenue-based finance for UK founders. £500 to £250k, no personal guarantees, shared upside instead of dilution.
Populai
BuildingA synthetic-judgment engine that pressure-tests decisions against hundreds of realistic personas before you commit.
Advisory
We build for ourselves. We advise so you build better.
The same operating discipline that runs the studio is available to a small number of founders and operating teams each quarter. Decision intelligence, operational excellence, and venture architecture — applied to your hardest calls, not delivered as a deck. When the work fits a known shape, we run it as a structured programme.
Build only what survives.
Whether you want to use the platforms or work with the people who build them — start here.
